WHEEL FOR WHEELBARROWS.

SPECIFICATION forming part of Letters Patent No. 281,865, dated July 24, 1883.

Application filed June 5, 1883.

To aZZ whom it may concern.-

Be it known that I, LEVI H. GooDwIN, a citizen of the United States, residing at Cincinnati, county of Hamilton, State of Ohio, have invented certain new an d useful Improvements in Wheelbarrows, of which the following is a specification.

The object of my invention is to make a strong, durable wheel that can be quickly and cheaply made without waste of material. This object I accomplish by the means illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a wheel e111- bodying my improvements. In this view some of the fellies and one of the clamping-flanges are removed, to more clearly show the construction. Fig. 2 is an enlarged diametrical section through one of the continuous spokes and the flanges which clamp them together and form the hub of the wheel. Fig. 3 is a perspective view of some of the severed fellies placed in the position they occupy in the stick from whichthey were severed. Upon one side is also shown one of the'short spokes detached.

The fellies A are severed from strips which have been previously dressed to the proper width and thickness. The mechanism for severing thefellies consists of two small circular saws, which are mounted upon two horizontal mandrels placed at an angle to each other. The mandrels have their bearings in a verticallysliding sash, one mandrel being a little above the other, so that when the sash is brought down one saw cuts a little in advance of the other, so that a sharp-angled V-shaped cut may be made without danger of the teeth of the opposite saws striking. The bed upon which the stuff is fed to the saws is on an angle to the plane of the axes of the saws. The angle depends, of course, upon the number of fellies in the wheel. In the example shown there are eight fellies, and the incline of the bed should of course be at an angle of one hundred and twelve and a half degrees to the planes of the saw-axes. The strip, resting on its edge upon the inclined bed, is fed under neath the saws, when, by a treadle or other suitable movement, the sash carrying the saws is brought down, severing one felly from the strip. When the treadle is released, the sash is thrown up bya weight or spring movement (No model.)

and the stick or strip turned over, bringing its opposite edge upon the bed and again fed forward under the saws the proper length for another felly. This operation is continued until the strip is used up. Underneath the tail or bed is arranged a bit to bore the hole for the dowel formed upon the end of the spoke. This bit is arranged to be carried up simultaneously with the descent of the sash which carries the saws.

Instead of the machine above referred to for cutting the felly-j oints and boring the hole for the spoke-dowel, my joint can be made upon the bed of an ordinary jointing-saw having the customary mandrel below the bed and working through it, but the mandrel inclined with relation to the bed, and another mandrel inclined in the opposite direction, mounted above the bed, the mandrcls being placed in different vertical planes, so that one saw will cut in advance of the other, as the ordinary circular mill-saws are arranged. The guide upon the bed is of course so placed that the strip will be fed to the saws at an angle to the axes of the saw-mandrels, so that the V-shaped end of the fellies will be on the radii of the wheel.

The cheek-plates B B, having the screwthreaded sleeves, are the same as shown in my patent of January 11, 1881; but the spokes in my present wheel are differently arranged, and by this arrangement I am enabled to make a stronger and better wheel at a less cost of production.

The spokes O G are continuous and gained together in the middle, after which they are bored centrally to receive the sleeve of the cheek-plate B. The spokes D are short, and have their inner ends beveled from each edge to the center, the beveled parts being at right angl es to each other, to fit into the angle formed by the spokes O O. XVhen the cheek-plates B B are tightly clamped up 011 the sides of thespokes,

the inner ends are held firmly in place. In fitting up my wheel the spokes are first clamped between the cheek-plates, the fclly-sections A are then driven onto their dowels 011 the ends of the spokes and clamped together in a suit able press to bring the joints up close, after which the perimeter, which is octagon-shaped, is dressed to a circle by a band-saw. The exterior sleeve of the face-plate, fitting a hole 9 acres;

1. The felly-sections A of the wheel, formed With V shaped meeting surfaces, the one matching into the other, so as to prevent lateral displacement, substantially as described.

2. In a Wheelbarrow-wheel, the combination, substantially as specified, of the fellysections and side-clamping cheelcplates, with the continuous spokes C, matched together in the center, and short spokes D, beveled at their inner ends, so as to rest in the angle formed by the spokes O, and having their inner ends clamped by the faceplates, substair tially as specified.
